BRUSH-BAND.

SPECIFICATION forming part of Letters Patent; No. 310,717, dated September 27, 1887.

Application filed March 18, 1886. Serial No.195,738. (No model.)

To aZZ whom. it may concern."

Be it known that I, SAMUEL A.VERBRYCK, a citizen of the United States, residing in Belleville, Essex county, New Jersey, haveinvented certain new and useful Improvements in Brush-Bands, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

My invention consists in a collapsible sheetmetal band of particular construction for retaining the bristles upon flatbrushesthe band being constructed in two parts, each formed with a loop to fit the edge of the brush, and with two flat ends to extend along the sides of the brush, and adapted to overlap and to slide upon one another when compressed in the manner described herein, so that the overlapping ends may be secured together while the brush and band are under compression.

Heretofore bands have been made in two parts; but such parts have not been made of similar form and adapted separately to fit the opposite edges of the brush and provided with overlapped ends upon both the fiat sides of the brush. Bands have also been made in one piece adapted to wind around the bristles,and to have their ends secured together by overlapping,and solid bands have been compressed upon the brush to upset the edge of the band.

My invention does not, therefore, consistin forming a band merely withoverlapping ends or in compressing it upon the brush, butin the formation of the band in two parts fitted separately to the edges of the brush, and adapted for application to brushes of various widths, byreason of the flat overlapping ends which lie upon the fiat sides of the brush, and are adapted to slide upon one another to any extent before fastening.

My construction is also especially adapted for compression simultaneously upon the edges and sides of the brush, as the separate loops at the opposite ends of the divided band are not deformed by such pressure; but the contraction is effected chiefly by the sliding of the flat ends upon one another.

A special apparatus is illustrated in the drawings for applying pressure simultaneously to different sides of the band; but my invention may be practiced by any other suitable apparatus, and I have not claimed herein that which is shown in the drawings, as I have heretofore patented a suitable machine for such purpose on May 4, 1886, No. 341,189.

Figure l of the drawings shows a plan of the apparatus operating upon a brush, the upper part of the block being removed to avoid obscuring the band. Fig. 2 is a side elevation of the same parts. Fig. 3 is an end view of the left-hand end of such apparatus. Fig. 4 is a side elevation, and Fig. 5 a plan, of a collapsible band made in two sections. Fig. 6 is a perspective View of the bristles and band applied to a plug, the bristles and band being broken away at the nearer corner to expose the plug; and Fig. 7 is a perspective view of the brushblock adapted to drive out such plug and replace the same within the bristles before the band is secured thereto.

The band, as shown in Figs. 4 and 5, consists in two bent loops of sheet metal applied to the brush with their ends overlapped, and adapted to yield when compressed at different points upon the brush, so that the overlapped ends may slide upon one another and be retained in such condition by inserting one or more nails into the block through the ends where thus lapped.

In the drawings the entire band is shown'of the oblong form required for a flat brush, and made in two parts, a a, having curved loops, with overlapping ends I) at the opposite flat sides thereof.

I Oorrugations c c are formed around the band longitudinally to stifien and ornament the same, and a row of holes, d, is formed in the hand between the corrugations to receive a series of nails for firmly securing the band to the block. The corrugations also serve to keep the edges of the overlapping ends even with one another by guiding them during their application to the brush and compression thereon, and they also serve partially to hold the two parts of the band in place when handling them together. As such a strip of sheet metal is quite flexible, it is obvious that when pressed against the ends and sides of afiat brush-block it would tend to clamp all the bristles equally upon the same, and that the tension induced by such pressure would be permanently retained by securing the overlapping ends of the I band to one another and to the brush-block by inserting a nail through each of such ends into the block.

I find it convenient in practice to lay up the bristles upon a plug, as at F in Fig. 6, the bristles E being laid thereon and the band G being applied over the same by first wrapping a piece of smooth paper around the points of such bristles and slipping the band over such paper with its overlapping ends secured movably by a thin clip, t'. Such clip is indicated in dotted lines in Figs. 4 and 5, and at 1' upon the lower side of the band in Fig. 6. The bristles are then ready for application to the block by the following process: The bristles are grasped firmly by their points, and the brushblock H, formed with a tapering point, as shown at h in Fig. 7, is forced into the space occupied by the plug, pushing the same farther down between the bristles, whence it is afterward easily removed. The band is then subjected to pressure, by any suitable means, upon its fiat sides and rounded ends simultaneously, and the band pressed firmly upon the bristles and the block, thus forcing the overlapping ends past one another to the utmost extent. Vhile thus held under compression, the overlapping ends are nailed to the block by inserting one or more nails through each, and the pressure is then relaxed and the brush removed from the compressing apparatus. The same process may then be repeatedupon another brush, and the remainder of the nails required to secure the band permanently to the block through the bristles may be applied at any convenient time.

The apparatus shown herein for compressing the band consists in four jaws, 0, formed with inclined bases and fitted by dovetails 0 into tapering sockets 7; 7c. The opposed jaws at each flat side of the brush are fitted together with a slot and tongue, Z, and the interior of the fourjaws is shaped to fit the exterior of the band.

Notches m are formed in the jaws to avoid the clips t, which, being of soft metal, may be readily pulled off after the jaws have clamped the band.

The socket k is mounted upon a pivot, a, in a horizontal bearing, 1), and the socket k is swiveled upon the point of the screw 0 in a similar bearing, 1).

A hand-wheel, q, upon the end of the screw furnishes the means of pressing the sockets toward one another, and the inclined bearings of the jaws in the sockets operate to compress the band longitudinally and laterally at the same time.

Holes 8 are formed at several points in the jaws c to admit a nail, and the overlapping ends of the band may thus be secured to one another and to the block under compressionin the jaws.

The mounting of the sockets upon the pivot n and screw 0 enables the operator to turn either side of the brush uppermost, and thus to apply a nail at the desired point through either of the holes s by means of asmallpuneh.

The bristles would of course be provided with glue to secure them to the block before the band is compressed upon them, and the butts of the bristles would afterward be covered with cement or varnish, or finished in any other desired manner.

I am aware of the state of the art shown in United States Patents Nos. 171,406, 33,010, 230,277, 327,723, and in British Patents Nos. 638 of 1857 and 4,017 of 1877, and hereby disclaim the constructions shown therein, or any construction merely involving the clamping of a continuous band upon a brush. My invention differs from any such constructions in the use of a band constructed in two parts, each of which has a curved loop and projecting ends adapted to lie upon the sides of a flat brush and to be overlapped thereon and nailed together and to the brush-block while under pressure.

I also disclaim United States Patent No. 341,189, which I have assigned to other parties.

Having thus set forth the nature of my invention, what I claim herein is- A collapsible sheet-metal band for flat bristle brushes, constructed of two similar parts of SAMUEL A. VERBRYGK.
